Cognition vs Cursor Rules
Cursor Rules bundle prompts, scripts, and workflows into project, user, or team rule files that load at the start of model context. Cognition stores approved skills outside the repo and serves them through MCP when a task matches.
Last reviewed 2026-11-03. Competitor details cite public docs below.
Cognition is for
Cursor users who also use Claude Code, Codex, or Gemini and want the same reviewed judgment everywhere, not only inside Cursor chat.
Cursor Rules is for
Teams standardized on Cursor Agent who need path-scoped rules, Team Rules on supported team plans, or simple AGENTS.md in the repo root.
Side-by-side
Honest comparison on what each product publishes today. This is not a scorecard.
| Aspect | Cognition | Cursor Rules |
|---|---|---|
| Mechanism | MCP tools (cognition_assist, skills) called during agent work | Rule text injected into context (Team, Project, User, or AGENTS.md) |
| Storage | Hosted Postgres-backed skill store keyed to your brain address | .cursor/rules/*.mdc in git, user rules in Cursor, team rules in dashboard |
| Application | Agent chooses tools; skills can require confirmation | Always apply, intelligent apply, globs, or manual @-mention |
| Tab and completions | Does not replace Cursor Tab; focused on agent workflows | Rules apply to Agent (Chat); docs state rules do not affect Tab |
| Sharing | Org-visible skills after approval; keys are revocable | Project rules via git; team rules via Cursor admin |
| Living updates | Capture workflows from real tasks into new skills | Edit rule files or run /create-rule when patterns repeat |
When to pick the other tool
- Every contributor uses Cursor and you want zero external services for standards.
- Your guidance is prompt-sized (under a few hundred lines) and repo-specific.
- You rely on glob-scoped rules tied to file paths in this codebase only.
How they work together
- Use Cursor Rules for file-type conventions and @-referenced templates in this repo.
- Connect the Cognition MCP server in Cursor and keep a short rule that tells the agent to call cognition_assist at session start.
- When a rule grows into a multi-step workflow reused across repos, save it as a Cognition skill and slim the rule down to a pointer.
